A COMPARISON OF YIELDS IN THE WHITE MOUN- 

 TAINS AND SOUTHERN APPALACHIANS. 



By K. W. Woodward. 



Very early in the examination of lands for purchase under the 

 provisions of the Weeks Law it was apparent that the average 

 stand in the White IVIountains exceeded in volume the average 

 stand on lands examined in the Southern Appalachians. By 

 reason of the varying degrees of culling and damage which have 

 taken place in the different regions and in different stands in the 

 same region it is obvious that a fair comparison can only be 

 made between unaffected virgin stands. Assuming then that 

 only undamaged virgin stands are to be taken into consideration, 

 the average stand per acre for the Southern Appalachians, in- 

 cluding all types is estimated to be 4,600 board feet. This esti- 

 mate is based on the following data: 



Percentage of Area Occupied by Types. 



Cove type 5% 



Slope type 55% 



Ridge type 40% 



100% 



Average Stcmds per Acre in Virgin Stands, Including By-products 



Such as Ties, Pulpwood, etc. 



Cove type 10,000 bd. ft. 



Slope type 6,000 " " 



Ridge type 2,000 " " 



Calculation of average Stand per Acre for Virgin Conditions. 



Cove type, 10,000 bd. ft. x 5% 500 bd. ft. 



Slope type, 6,000 bd. ft. x 55% 3,300 " " 



Ridge type, 2,000 bd. ft. x 40% 800 " " 



4,600 " "
